| This paper studies the relationship of biological tissue character and the fast Fourier transform (FFT) spectrum of Polarization-sensitive optical coherence tomography (PS-OCT) signal, revealing the influence of tissue birefringence, texture and structure. After describing the single-detector PS-OCT imaging theory in detail, this paper simulated FFT spectrum of PS-OCT A-scan signal with a three-layer tissue model as sample, whose parameters varied during simulation, and analyzed the influence of different model parameter on FFT spectrum. The simulation results showed that, with different tissue character, the FFT spectrum figure will have different shape and center frequency of side peaks. This research validated the ability of single-detector PS-OCT detecting multiple biological tissue character, widening the usage of PS-OCT. |
